Anyone got an earlier edition? Not of that book, but similar wording in ARRL's 1972 "VHF Manual". I found it, but not the book I was looking for. You're right, page 179: "Another matching trick with the ground-plane is to droop the radials downward, adjusting their angle below the horizontal until the antenna feed impedance becomes 52 ohms. This usually occurs at about a 45-degree angle." -- 73, Cecil http://www.qsl.net/w5dxp ----== Posted via Newsfeeds.Com - Unlimited-Uncensored-Secure Usenet News==---- http://www.newsfeeds.com The #1 Newsgroup Service in the World! 100,000 Newsgroups ---= East/West-Coast Server Farms - Total Privacy via Encryption =--- |
